Bei der Herstellung von Kreuzbodenbeuteln lag der hierzu benutzte Papierschlauch platt, und die fertigen Beutel gingen imGebrauch nur seltengut auf.The one used for this purpose was in the manufacture of cross-bottom bags Paper tube flattened and the finished bags rarely opened well in use.
Diesen Nachteil beseitigt nun, die erfindungsgemäße Maschine, die namentlich dadurch gekennzeichnet ist, daß sie in der Reihenfolge des Herstellungsvorganges der Beutel folgende Bauteile aufweist: eine die Papierbahn von der Druckvorrichtung übernehmende, quer zur Ablaufrichtung der Papierbahn angeordnete Querfalzvorrichtung, eine Klebstoffauftragevorrichtung, Z,ängsfalzräder und einen Doppeltisch für die Bildung des blasebalgartig zusammengelegten Schlauches, eine aus einer Walze und zwei Preßrollen bestehende Abzugsvorrichtung mit unterhalb derselben. anschließendem Schlauchaufweiter, der zunächst den Balg auszieht und alsdann mit einem Fortsatz den Papierschlauch wieder flach streckt derart, daß die inneren Falze des Balges die äußeren Ränder des platt gestreckten Schlauches bilden, der alsdann durch ,Abzugswalzen einer Schervorrichtung zugeführt wird, worauf die abgetrennten Beutellängen zur Maschine für die Fertigstellung des Beutelbodensweiterwandern.This disadvantage now eliminates the machine according to the invention, the is specifically characterized in that they are in the order of the manufacturing process the bag has the following components: a the paper web from the printing device receiving cross-folding device arranged transversely to the direction of run-off of the paper web, an adhesive applicator, Z, longitudinal folding wheels and a double table for the Formation of the bellows-like folded tube, one from a roller and two pressure rollers existing take-off device with below the same. subsequent Hose expander, which first pulls out the bellows and then with an extension stretch the paper tube flat again so that the inner folds of the bellows form the outer edges of the flat stretched tube, which then passes through take-off rollers a shearing device is fed, whereupon the separated bag lengths to Machine for completing the bottom of the bag.
Die zur Beutelherstellung benutzte Papierbahn kann selbstverständlich auch meh:rlagig sein. Weitere. Merkmale der Erfindung ergeben sich übrigens aus nachstehender !&eschreibung der in der Zeichnung veranschaulichten Ausführungsbeispiele, und zwar zeigt Fig. i ein erstes Ausführungsbeispiel in schaubildlicher Ansicht, Fig. 2 ein zweites Ausführungsbeispiel im Seitenriß, Fig.3 die Draufsicht eines Maschinenteiles zu Fig. 2, Fig.4 bis 14 die einzelnen Herstellungsphasen eines Papierbeutels.The paper web used to make the bag can of course be used also meh: rlagig. Further. Features of the invention result Incidentally, from the description below of the one illustrated in the drawing Exemplary embodiments, namely FIG. 1 shows a first exemplary embodiment in diagrammatic form View, FIG. 2 shows a second exemplary embodiment in side elevation, FIG. 3 shows the plan view of a machine part to Fig. 2, Fig. 4 to 14 the individual manufacturing phases of a Paper bag.
Wie Fig. i veranschaulicht, läuft die beispielsweise von der Druckmaschine kommende Papierbahn i zwischen, den beiden Walzern 2, 3. Die Walze 2 ist mit einem Gummiüberzug versehen, während die Walze 3 eine Leiste 4 trägt:, die zum Einprägen des Beutelbodenquerfalzes 5 (Fig. ii und 12) dient. !Die Papierbahn wandert alsdann zur Klebstoffauftragevorrichtung 6, die sich aus der Walze 7, der Scheibe 8 und der Klebstoffmuldie 9 zusammensetzt. Durch diese Vorrichtung wird der Klebstoff auf den einen Rand To der Papierbahn (Fig.4) aufgetragen.As FIG. I illustrates, it runs, for example, from the printing press coming paper web i between, the two rollers 2, 3. The roller 2 is with a Provided with a rubber cover, while the roller 3 carries a bar 4: which is to be embossed of the bag bottom transverse fold 5 (Fig. ii and 12) is used. ! The paper web then wanders to the adhesive applicator 6, which consists of the roller 7, the disc 8 and the adhesive mold 9 is composed. Through this device the glue applied to one edge To of the paper web (FIG. 4).
Die Papierbahn läuft nun über Falzräder i i, die die Bildung zweier Längsfalze 12, 13 (Fig. 5) vorbereiten. Zwei von einer Stütze iß getragene Blechtafeln 14, 15, die mit ihren Enden i4a, 15' aufeinander zulaufen, erzeugen die vier parallelen Längsfalze 16, 17 (Fig. 6).The paper web now runs over folding wheels ii, which prepare the formation of two longitudinal folds 12, 13 (FIG. 5). Two metal sheets 14, 15 supported by a support, the ends 14a, 15 ' running towards one another, produce the four parallel longitudinal folds 16, 17 (FIG. 6).
Das Papier läuft alsdann zwischen der Walze i9 und den beiden -Anpreßrollen 2o, die gleichzeitig Abzugsrollen bilden und die Falze 12, 13, 16 und 17 einprägen. Ein entsprechend zugeformtes Blechstück 21 greift in den bal.gförmig zusammengefalteten Schlauch (s. Fig. 7) ein. Dieses Blechstück hat zunächst die _ Breite -des. _ Papierbalges, wird in seinem zugeründeten Teil a14 allmählich breiter und hat schließlich die Breite des flach gezogenen Schlauches, den es bilden soll (Fig. 8, 9 und To).The paper then runs between the roller 19 and the two pressure rollers 2o, which simultaneously form take-off rollers and impress the folds 12, 13, 16 and 17. A correspondingly shaped piece of sheet metal engages in the folded bellows Hose (see Fig. 7). This piece of sheet metal initially has the _ width -des. _ Paper bellows, becomes gradually wider in its rounded part a14 and finally has the Width of the flat drawn tube that it is to form (Fig. 8, 9 and To).
Der Schlauch läuft alsdann zwischen( einer Abzugswalze 22 und den Rollen 23, 24 zur Schervorrichtung, die aus einer Walze 26, einem mit dieser umlaufenden Messer 25 und einem festen Gegenmesser 27 besteht. Hier wird der Schlauch in Beutellängen unterteilt. Die abgetrennte Beutellänge wird nun zur Maschine gefördert, die den Beutelboden erzeugt (Feg. 11, 12, 13). Es fällt nun ein Beutel 28 (Feg. 14) an, der im wesentlichen-, ddieselbe Form wie die sogenannten amerikanichen Beutel hat.The hose then runs between a take-off roller 22 and the rollers 23, 24 to the shearing device, which consists of a roller 26, a knife 25 rotating with this and a fixed counter knife 27. Here the hose is divided into bag lengths conveyed to the machine, which produces the bottom of the bag (Fig. 11, 12, 13). A bag 28 (Fig. 14) is now produced, which has essentially the same shape as the so-called American bags.
In der Ausfiiihrungsart gemäß Fig.2 läuft die Papierbahn zunächst über eine Abzugswalze 30, als,danh: über Falzräder 31, die die Bildung zweier Längsfalze 12, 13 (Feg. 5) vorbereiten. Das Papier läuft alsdann über.zwei an einem Träge-r34 sitzende Blechtafeln 32, 33 (Feg. 3), die mit ihren Enden 32a, 33d aufeinander zulaufen und die vier parallelen Falze 16, 17 (Fig. 6) bilden.In the embodiment according to FIG. 2, the paper web first runs over a take-off roller 30, as, then: over folding wheels 31, which prepare the formation of two longitudinal folds 12, 13 (Fig. 5). The paper then runs over two sheet metal panels 32, 33 (Fig. 3) seated on a carrier 34, the ends 32a, 33d of which converge and form the four parallel folds 16, 17 (Fig. 6).
Das Papier läuft nun zwischen einer Preßwalze 35 und Preßrollen 36, die zugleich den Abzug des Papiers bewirken. Der talgartig zusammengefalzte Schlauch ist alsdann, vollständig fertiggestellt (Fig.7), wird dabei von der Maschine abgelenkt und vom Blechstück 37 (Fig. 2 und 3) aufgeweitet und wieder platt gezogen (Fig. To).The paper now runs between a press roller 35 and press rollers 36, which at the same time cause the paper to be withdrawn. The tube folded up like sebum is then completely finished (Fig.7), it is distracted from the machine and expanded by the sheet metal piece 37 (Fig. 2 and 3) and pulled flat again (Fig. To).
Der vollkommen platte Schlauch wird von einer Walze 38 und Preßrollen 39 einer umlaufenden Schervorrichtung zugeführt, die bei jeder Umdrehung eine Beutellänge abtrennt. Anschließend erfolgt die Bildung und Schließung des Biodens (Fig. 11, 12, 13), so daß der fertige Beutel 28 (Fig. 14) im wesentlichen; die Form eines amerikanischen Beutels aufweist.The completely flat hose is from a roller 38 and pressure rollers 39 is fed to a rotating shearing device, which is one bag length with each rotation separates. Then the formation and closure of the biodies takes place (Fig. 11, 12, 13), so that the finished bag 28 (FIG. 14) essentially; the shape of a American pouch.
Die beiden dargestellten: und beschriebenen Ausführungsbeispiele gestatten die kontinuierliche Herstellung ein- und mehrlagiger Beutel.The two illustrated and described exemplary embodiments permit the continuous production of single and multi-layer bags.
